Figure 17. The zone reports that can be generated when using sound reinforcement.
The zone matrix report is a spreadsheet that summarizes the zone reinforcement

zone inputs and outputs, zone reinforcement crosspoints, and the devices that
inputs are connected to is shown in Table 1. The zone matrix report is created at
